Mu Yuncheng and Crazy Rabbit Smoke followed the compass pointer to the door of a restaurant, and the pointer was facing a table in front of a young man who was eating.

The young man had a delicate face, a white coat and a green shirt, and at his feet lay a wooden box with two huge scrolls showing in half.

Mu Yuncheng was afraid that he would not be sure, so he let Yan Rong take the compass and circle around the young man, and the pointer fruit kept pointing at the young man, and he never deviated from it at all.

The young man also noticed the strange behavior of the two, and then raised his eyes to look at Mu Yuncheng, revealing a vigilant gaze.

When the young man wanted to reach for his wooden box, Mu Yuncheng hurriedly explained, "Don't worry, we have no malicious intent. ”

The young man held his breath and slowly withdrew his hand, still looking at the two of them in disbelief.

"You're Wu Fan's grandson, right?" Mu Yuncheng asked seriously.

The young man nodded, put his hands behind his back honestly, and asked weakly, "How do you know this, and why did you come to me?"

"Yes, we want to ask you for help, can we dare to ask your name?" Mu Yuncheng immediately smiled, which also made the young man let go of his vigilance.

"Wu Qi. The boy replied earnestly.

"Wu Qi? I see. Mu Yuncheng nodded, then sat down opposite him, and said with a clear intention: "We came to you to ask you to help build a kind of artillery, which is very powerful and can be used to defend Wanghai City." ”

"Do you want to make artillery?" Wu Qi lowered his eyes, but he was a little unconfident.

"Yes, I think you'll be up to the task. Mu Yuncheng said affirmatively to him, and handed him the drawings in his hand.

Wu Qi took the drawing, but as soon as he glanced at it, he stood up from his seat in surprise: "This is the Red Cloud Cannon! How can you have this drawing?"

"If you do, it's even better. Mu Yuncheng breathed a long sigh of relief and continued to explain: "This drawing was designed by a friend of mine based on his memory of seeing the Red Cloud Cannon. ”

Wu Qi carefully looked at the drawings again, and then shook his head slightly and said: "Although the Red Cloud Cannon has been carried forward in the hands of the Torture Demon, its core idea was conceived by my grandfather in his old age, so according to my understanding of the Red Cloud Cannon, there is a big problem with your friend's drawing! If the artillery designed according to this drawing cannot be regarded as the Red Cloud Cannon at all. Because he didn't grasp the most critical core in this. ”

"Huh?" Mu Yuncheng and Yanwei glanced at each other, both expressing puzzlement.

"The Red Cloud cannon is known for its wide range and great power, so the main gun track is not as straight as shown in this picture, but a honeycomb hole-like inner multi-barreled gun track. As a result, the entire drawing was misdesigned. As an example, while both guns are tail loaded, the reloading mechanism of the Honeycomb Rail requires an octagonal chassis to stabilize it. In this way, it is possible to ensure that the gunpowder will not go off after the explosion of the inner chamber. For a while, I couldn't explain these issues clearly to you. ”

And after listening to Wu Qi explain the principle of the real Red Cloud Cannon, Mu Yuncheng suddenly felt that he had found the right person today. If you don't find him, just relying on Mo Yiyue's drawing, I'm afraid that you won't be able to make a real Red Cloud Cannon in your lifetime.

"That being the case, we will depend on you how you say to change, but now that time is pressing, I hope you can still come with us. Mu Yuncheng stood up, noticed the wooden box under Wu Qi's feet, and picked it up casually.

This one is not tight, so it almost didn't tear Mu Yuncheng's waist off.

Mu Yuncheng hurriedly let go of his hand: "What's in here, it's so heavy!" From the outside, there was nothing in there at all, just two scrolls. This scroll can't be so heavy, right? Besides, looking at Wu Qi's small physique, he is not as strong as himself, how can he carry such a thing around?

Wu Qi hurriedly explained to Mu Yuncheng and said: "This box is a treasure left by grandpa, there is a mystery hidden in it, there is nothing from the outside, but there are so many things that can be contained inside that it is scary to death." How can I not sink all my belongings in this box?" and he crouched down, put his arms into the strap of the wooden box, and then got up, and carried the box behind him with a light weight.

Mu Yuncheng still didn't understand, but he felt that this box was really a hidden mystery, which was beyond the comprehension of a layman like himself.

At this moment, on the side of Zuotun Camp, Shi Fubing had already arranged manpower, and was waiting for Mu Yuncheng to explain the next step, but he couldn't find Mu Yuncheng after searching left and right. I heard that Mu Yuncheng had just gone out with a rabbit, and he hurriedly sent people to look for it, but at this anxious moment, Mu Yuncheng and Wu Qi rushed back from outside.

"The staffing is already in place, and I would like to give you clear instructions on what to do next. Shi Fubing breathed a sigh of relief and hurriedly reported to Mu Yuncheng.

Mu Yuncheng looked down at Wu Qi, Wu Qi understood what he meant, and then asked, "Are all the materials used to build the cannon ready?"

"This ...... Now that the resources in the city are tight, in addition to the copper and iron utensils in the treasury, I have also collected the materials of all the blacksmith shops in the city. Originally, these were meant to make weapons, but if you want to build a cannon, I really don't know if it's enough. Shi Fubing pointed to the mountain of metal utensils at the back of the camp, but they all needed to be melted before they could be forged.

Even the stove for burning the fire is among them.

"How many people should be smelted, how many people will build, and how many people will assemble ......."

Mu Yuncheng heard that his head was big when he heard this, he really wasn't this piece of material, how should he answer this? Just when Mu Yuncheng was at a loss, he saw Wu Qi smile faintly and said confidently: "I don't need to be alone, I can just come by myself." ”

"What!" Mu Yuncheng and Shi Fubing were both taken aback when they heard this, this kid is too ignorant of the sky, how can he complete such a large workload on his own?

I saw Wu Qi squatting down and unloading the wooden box, taking out a scroll from it, placing it on the ground and spreading it out in front of everyone.

No one knew how long the scroll was, but Wu Qi spread it out carefully and stopped. Mu Yuncheng hurriedly approached to take a look, only to find that all the paintings inside were strange things.

"Let's use the third uncle of civil construction and the casting Shichiro!" he seemed to be talking to himself, but as he slid his finger over the monster drawn in the drawing, the scroll instantly erupted with a blinding light like the sun, and only two heavy landing sounds could be heard. When everyone opened their eyes again, the monsters drawn in two places in the scroll had disappeared out of thin air. Mu Yuncheng hurriedly raised his eyes to look, and sure enough, two giant monsters with a height of several people suddenly appeared behind Wu Qi, only to see that their bodies were made of fine iron, which was surprisingly similar to the sword dragon!

"Let's take a space first, and please stay back. Wu Qi, who started to work, has completely lost his previous shyness, as if he was injected with endless enthusiasm in an instant.

Everyone present, except for Wu Qi himself, was not so much surprised at the moment as shocked. Anyone who has ever seen this kind of construction scene can't help but admire Wu Qi for what a ghost!

Seeing that the giant monster known as the third uncle of civil construction was the best at digging soil, and dug a huge deep pit in the camp in an instant, Mu Yuncheng looked at it and exclaimed: "This monster is so sharp, such an efficiency, I am afraid that it is difficult for everyone present to start working together." ”

And the casting Shichiro had already pushed all the copper and iron that had just piled up into the earth pit.

"They're not monsters, they're machines, they're my friends! Wu Qi suddenly thought, and pulled out another scroll from the wooden box, and when it was unfolded, there were all kinds of large utensils painted inside.

What furnaces, bellows, iron piers, even windmills.

Watching Wu Qi move the things inside out of thin air one by one, Mu Yuncheng was even more shocked when he saw it.

How many things can be hidden in these two scrolls!

"Finally, it's water. Wu Qi pondered for a moment, then summoned a giant gopher-like machine from the scroll and said to it, "Breaking Ground Hachiro, go and bring in some seawater." ”

The two huge front paws of the mechanical gopher were forged of stainless steel, and they could refract light in the sunlight, so why not be sharper than a sword!

This scene seems to be familiar, and in the past, in Jiangzhou City, the sword also led the river water to extinguish the gunpowder in the secret room.

This Breaking Hachiro moves extremely fast, making a rumbling sound like thunder when working underground, and the sound becomes more and more subtle from near to far. And in only half a pillar of incense, the sound of thunder vibrating came back clearly. Then a huge figure jumped out of the pit, it was Breaking Ground Hachiro.

It looks like the mission is well done.

Before he could praise the "gopher", a trickle seeped out of the hole, and the water was slowly filling the pit that had just been dug.

Mu Yuncheng stepped forward and gratefully touched Tu Hachiro's big paw, but saw it suddenly lying on the ground, honestly guarding Wu Qi's side. Everyone didn't know what to say for a while, so they had to cast approving and admiring glances at Wu Qi.

In this way, the construction of the Red Cloud Cannon can be said to be in place.
